Hot Water & Booster Heaters

Hot Water & Booster Heaters

This category covers hot water & booster heaters designed for use with unheated professional pressure washers, such as cold water systems within Kärcher’s professional HD range, providing an effective way to introduce heat into cleaning processes where cold water alone is not sufficient. Booster heaters raise the incoming water temperature before it reaches the point of use, improving the breakdown of oil, grease, fats, and heavy contamination while reducing cleaning time and chemical usage. These systems are commonly integrated into fixed or mobile professional setups, supporting applications such as vehicle washing, workshop cleaning, industrial plant maintenance, and agricultural use. Hot water and booster heater units are engineered for continuous operation, featuring durable heating coils, reliable burners or electric heating elements, and built-in safety controls to maintain stable and controlled temperature output. Correct integration is essential, as these heaters are designed to operate within defined flow rates, pressure limits, and connection standards to ensure safe and efficient performance. When installed correctly, booster heaters allow cold water pressure washers to be upgraded to hot water capability without replacing the entire machine. As part of a professional cleaning setup, hot water & booster heaters support scalable installations, enabling improved cleaning efficiency across single or multiple wash points where consistent heat delivery is critical.
